Of course, but not simply because people are still in school as you or someone else stated. Students were in school in all years past which hasn't changed. Your comparison really doesn't make sense.
Well, obviously they have decided to make a change to the usual promotion. I think he was just speculating. June 1 does seem to be about the earliest "back to school" promotion of any company I have ever heard of.
At this point we don't have any idea if it is delayed, going to be changed significantly, or just not run. I would guess changed somewhat and run in the summer, not the spring and summer.
